Application filed. June 16, 1914. Scriahlmflfldfi,

To all whom it may concern:

Be it known that I, WILLIAM B. Genus, a citizen of the United States of America, and resident of Wheeling, county of Ohio, and State of West Virginia, have invented certain new and useful Improvements in Orchard-Heaters,, of which the following is a specification.

Thisinvention relates to orchard heaters, and it has for its primary object to provide a simple and efiicient heater of the oil-burn ing type having means whereby the rate of combustion may be regulated and, consequently, whereby the heat radiation may be controlled A further object is to provide a device of the character mentioned which is devoid of complication, which is comparatively inexpensive to manufacture and which is designed to produce combustion of a highly eflicient character.

In describing the invention iii-detail, reference is herein had to the accompanying drawings, forming a part of this specification, in whic Figure 1 is a view partly in side elevation and partly in vertical section; Fig.- 2 is a partial section on the line 2-2, Fig, 1; and ig. 3 is an enlarged detail section on the line 3-3, Fig. 2.

Referring to said drawings, in which designating characters distinguish like parts throughout the several views-1 indicates a receptacle or container for liquid fuel, said container being circular in torn; and preferably composed ofsheet metal. Located at a point adjacent to the upper end of said container is an annular inwardly directed crimp or bead 2 which constitutes a seat for the lower end or a low frusto-conical shield or false cover 3 which is open at both ends, as shown. Located at a point above the crimp or bead 2 is an outwardly directed annular crimp or bead 4 which constitutes a seat for the inner edge of the horizontal portion of a close-fitting ring 5 which embraces the upright flange-like upper end 6 of the contamer. Said ring 1s substantially L-shaped in cross-section, having an upright flange at the outer edge of said horizontalportion. Fitted closely to the said flange of said ring is the annular flange-like rim 7 of an upwardly tapered cover 8 having a central opening or passage 9 therethrough for permitting egress to a superposed stac 10 of the products of combustion arising from the l container through the upper end of the shield 3. Seated upon the horizontal portron. of said ring 5 is a circular ring 11 which is adapted to be rotated slightly for moving a plurality of perforations or apertures 12 provided therein into and out of registration with similar perforations or apertures 13 provided in the, said horizontal portion oil ring 5, said perforations or apertures being designed, when in register, to admit air which thence passes upward between the cover 8 and the shield 3 for fnixing with the uses issuing through the top of the latter or facilitating combustion of said gases within said stack.

Provided in the horizontal portion of the ring 5 is one or more short slots 14 through which project studs or pins 15 which are fixed in the ring 11, said studs or pins aiiording exposed means whereby said ring 11 may be engaged for eifecting its rotation, and said slots scrvingto limit the extent of rotation As is obvious, any desired degree of registration between the apertures 12 and 13 may be effected, and, as a consequence, the amount of air admitted may be regulated. Thus, means is afforded whereby the rapidity of consumption of the fuel may be accurately lated for producing the desired amount 0 heat generation.

As is obvious, the shield 3 may be more or less inclined with respect to the cover 8, or may be entirely dispwith. However, it has been found in: practice that slightly better combustion is accomplished when said shield is used, the air admitted being thereby directed upward'to a point where it mingles with the gases ata point near the base of the stack.

While the seats for the shield 3 and the ring darehereinshown as afiorded by the reversely disposed annular bead-like crimps 2 and 4, it will be apparent that this particular form of seats is not essential.

hat is claimed is- 1. An orchard heater comprising a circular. container, an external annular seat for on said container adjacent to its upper end, an apertured ring mounted on said seat, a second apertnred ring adjustably mounted on the first mentioned ring, a tapered cover having a central opening therein mounted over said container, said cover having a rim in en agement with one of said rings, and a stacE mounted on said cover about said opening.

2; An orchard heater comprising a circular container, an external annular seat formed on said container adjacent to its upper end, an apertured ring mounted on said seat,-'a second apertured ring adjustably mounted on the firstmentioned ring, a tapered cover having a central opening therein mounted over said container, said cover being seated upon one of said rings, and a stack mounted on said cover about said opening.

3. An orchard heater comprising a circular container, an external annular seat formed on said container adjacent to its upper end, an apertured ring mounted on said seat, a second apertured ring adjustably mounted on the first mentioned ring, a tapered cover having a central opening therein mounted over said container, said cover being seated upon one of said rings, a stack mounted on said cover about said opening, and an upwardly tapered shield having its lower end seated within and adjacent to the top of said container, said shield being open at both ends.

4. An orchard heater comprising a circular container, an external annular seat formed on said container adjacent to its upper end, an apertured, ring mounted on said seat, a second apertured ring adjustably mounted on the first mentioned ring, a tapered cover having a central opening therein mounted over said container, said cover being seated upon one of said rings, a stack mounted on said cover about said opening, and an upwardly tapered shield having its lower end seated within and adjaccnt to the top of said container, said shield being open at both endsand terminating at its upper end adjacent to the opening in the cover.

5. An orchard heater comprising a circular container, an external annular seat formed on said container adjacent to its upper end, a ring mounted on said seat, said ring having a horizontal apertured portion, a second ring adjustably mounted on the first mentioned ring and havin apertures for registration with those of tie latter, a cover having an annular rim seated upon one of said rings outside said apertures, said cover having an opening therein, and a stack mounted on said cover about said opening.

6. An orchard heater comprising a circular container, an external annular seat formed on said container adjacent to its upper end, a ring mounted on said seat, sald ring having a horizontal apertured portion, a second ring adjustably mounted on the first mentioned ring and having apertures for registration with those of the latter, a cover having an annular rim seated upon and having a portion embracing the first mentioned ring, said cover having a central opening therein, and a stack mounted on said cover about said opening.

7. An orchard heater comprising a circular container, an external annular seat formed on said container adjacent to its upper end, a ring mounted on said seat, said ring having a horizontal apertured portion, a sec? ond ring adjustably mounted on the first mentioned ring and having apertures for registration. with those of the latter, a cover having an annular rim seated upon one of said rings outside said apertures, said cover having an opening therein, .a stack mounted on said cover about said opening, and an upwardly tapered shield disposed below said cover and having. its lower end seated upon saidcontainer, said shield opening outward at its upper end adjacent to the opening in the cover.

8. An orchard heater comprising a circular container, an external annular seat formed on said container adjacent to its 'upper end, a ring mounted on said seat, said ring having a horizontal apertured portion, a second ring adjustablymounted on the-first mentioned ring and having apertures for registration with those of'the latter, a cover having an annular rim seated upon one'of said rings outside said apertures, said cover having an opening therein, a stack mounted on said cover about said opening, an internal annular seat formed on said container adjacent to its upper end,- and an upwardlytapered shield having its lower end resting on said internal seat, said shield opening outward at its upper end adjacent to the opening in the cover.

In testimony whereof, I aflix my signature in presence of two subscribing witnesses.
